(RAMP News)Still trying to understand what's happening with Facebook? Founder/CEO Mark Zuckerberg changed things again today, announcing major changes during his keynote at the F8 Conference. Included in a new series of enhancements and linked applications, as well as a new feed called "Timeline," he unveiled a new way that users can share music. In what he described as "realtime serendipity," Zuckerberg showed how users will be able to see what their friends are listening to via linked applications like Spotify and, if they want to hear it, can click on it in through Facebook to stream it as well -- which will show up in their own news feed, spreading it to other people and so on and so forth. Facebook is also rolling out a Music Timeline that shows a person's top artist, most-listened-to song and current playlist, allowing people to find out what you're hearing and sample it themselves.

He brought out Spotify Founder/CEO Daniel Ek, who spoke for a few minutes about how his company has integrated with Facebook to spread music -- in a good way. "We had to draw people away from piracy while helping them listen to more music," said Ek. "The problem with Napster was that it didn't work for the music industry. We spent the last decade building a product that benefits the artists while allowing people to share music." According to Spotify's figures, members listen to more music and more different kinds of music. "They're more engaged, so they're more than twice as likely to pay for music," Ek said. "We're bringing people back to paying for music again." Zuckerberg closed out the music portion of his presentation by showing a quick slide of the dozen or so applications that are being linked into Facebook's new music deal, including iHeartRadio, Turntable.fm and Rdio.
